Let me just mention something, since some people seem to be missing this point. The only one confirmed to be leaving is Casey. Nelson Branco said that he heard on the red carpet that Chandler and Camila will leave when their contracts are up. That's not confirmed by anyone other than Nelson, aside from a few other interviews Chandler did where he hinted at it. We have no idea whether they've told the show this, whether they've made up their minds, whether Nelson got the story right, or whether the show wants them to stay.
